Abstract

The present invention relates to a vehicle engine variable cycle brake slowing system; the system can make the brake pedal decelerate according to the depth of the brake pedal when the driver issues a deceleration instruction, the vehicle is not in neutral and the clutch is in a fully combined state. The engine changes the driving cam of the rocker arm of the exhaust valve corresponding to the corresponding cylinder in a timely manner, so that the corresponding cylinder changes from the original four-stroke cycle mode of intake, compression, expansion, and exhaust to the two-stroke cycle mode of intake, compression, intake, and compression. The stroke cycle mode makes the cylinder at this time become a more efficient air compressor, and consumes more inertial motion energy of the car by compressing air.

Description

1. Technical field [0001] The invention relates to a vehicle engine variable cycle brake retarding system, which is simpler in structure, more compact, lighter in weight, more perfect in function and softer in work than the known variable cycle brake retarder system of the automobile engine. 2. Background technology [0002] At present, the function of the known vehicle engine variable cycle slowing system is: when the vehicle's inertial operation requires slowing down, the drive wheel drives the engine to run through the transmission system. At this time, the engine can change the cycle mode, from the original air intake, compression, The four-stroke cycle mode of expansion and exhaust is changed to the two-stroke cycle mode of intake, compression, intake, and compression. The engine consumes the inertial motion energy of the car through compressed air, thereby reducing the running speed or reducing the running acceleration. The current variable cycle slowing system of auto...
